problems running viewer on Mac

Hi I am trying to run the viewer on my macbook. I can get the viewer and the dom to compile using the supplied xcode projects, however when I try and open any of the samples I get what looks like a bad VBOS number and eventually a seg fault

terminal output looks lie this:

main() demo.dae
COLLADA_RT Using VBOS 4786592
COLLADA_DOM Load Started file:///Users/Evan/collada-dom/viewer/bin/
COLLADA_DOM Runtime database initialized from file:///Users/Evan/collada-dom/viewer/bin/.

nameOnly: 0x17b2e9c
